WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 234,645, dated November 23, 1880.

Application filed June 18, 1880.

To all whom it may concern Be it known that I, DAVID K. ALLINGTON, a citizen of the United States, residing at East Saginaw, in the county of Saginaw and State of Michigan, have invented a new and useful Water -Heater, of which the following is a specification.

The object of my invention is to construct a water-heater in such a manner that the condensed steam or drip-water and vapor that escapes from a steam salt-works or other steam evaporatin g-works, and from leaks in the pipes, is salted or mixed with any foreign matter, so that it is unfit to return to the steam boilers and is run to waste; that the heat that it contransferred to the feed water to the boilers,

or the brine or other fluid, as it is run to the works.

In the drawings, Figure 1 is a plan view, and Fig. 2 a cross-section.

Like letters denote corresponding parts in all of the figures.

The pipe 0, Figs. 1 and 2, is provided at its opposite ends with theheads and stuffing-boxes e and c, and the inlet-pipe a and outlet-pipe c.

The pipe d, Figs. 1 and 2, is placed inside of the pipe b and runs its whole length, as is shown by the pipe I) being cut away at cl d d, and passes out through the stuffing boxes 0 and c, Fig. 1, the stufing-boxes allowing the pipe (I to slip, so as to relieve the pipes b and d from any strain that might be caused from unequal expansion.

The pipes b and d, Figs. 1 and 2, may be placed in a coil, or in a straight line, or any other form that will be most convenient for the purposes herein described, and in place of the pipe at there may be any desired number of pipes running through the pipe I), so that cold water or other fluid may be introduced at one end, and hot drip and vapor at the opposite end.

When the heater is used to heat the feedwater for steam-boilers, the cold water enters the pipe I) through the inlet-pipe a, and runs (No model.)

ducted to and enters the pipe (Z at f, Fig. l,

and runs its whole length, and is discharged and run to waste at g at the opposite end. By this in cans the cold water or brine, or other fluid, enters the heater at one end, and the hot drip-water and vapor from the evaporatingworks at the opposite end, and they run in opposite directions, so that all, or nearly all, of the heat that is contained in the, drip-water and vapor may be transferred to the feedwater to the steam-boilers,'or to the brine or other fluid that is to be evaporated in the evaporating-works.

The hot drip-water and vapor that enters the pipe at at f will discharge at g as cold, or nearly as cold, as the water or other fluid that enters the pipe I) through the inlet-pipe a, and the cold water or other fluid that enters the pipe b through the inlet-pipe a will, when discharged through the discharge-pipe c, be nearly or quite as hot as the drip-water and vapor that enters the pipe (I at f, thereby utilizing all or nearly all of the heat that is contained in the drip-water by transferring it to the feed-water for the steam-boilers, or to the brine or other fluid that is to be evaporated in the steam evaporating-works.

The cold brine or other fluid to be used in the evaporating works, or the feed-water forsteaIn-boilers, may be run through the pipe cl, and the hot drip-water and vapor run through the pipe b, they being introduced at opposite ends and run in opposite directions, so that all of the heat contained in the drip-water and vapor that is run through the pipe I) may be transferred to any fluid that is run through the pipe (I.

When the heater is laid in coil, instead of using the heads and shifting-boxes c e, I may use plain heads, the inside pipe, (I, being threaded with a long thread to screw through the head and receive a coupling on the out I and dischargepipe 0, in combination with the 10 side, from which the pipe may be continued to inner pipe, d, all constructed and arranged any desired point, the difference in the size of as shown and described, and for the purpose the pipes b and 01 being snflicient to relieve all described. strain from unequal expansion.

hat I claim as my invention is- The water-heater herein described, consisting of the outer pipe, I), provided with the heads and stufling-boxes e e, the inlet-pipe a, I
